Temporary vessel occlusion enables a surgeon dissect aneurysm and clip with a lower risk of intraoperative hemorrhage with the associated risk of ischemia. There are studies on permissible time of occlusion of the parent artery using temporary clip; however, the actual incidence of silent ischemic events in patients with aneurysms treated with microsurgical clipping is not well documented. We are trying to look for the association between temporary clipping and incidence of ischemia through this study. The study concluded the statistically significant association between the maximum time of single clip application and ischemia. Intermittent multiple temporary clippings can prevent ischemia instead of a single clipping of longer duration.
